Dimethylbis(pyrazine-2-carboxylato-κ2 N 1,O)tin(IV)

Abstract

In the title compound, [Sn(CH3)2(C5H 3N2O2)2], the SnIV atom is twice N,O-chelated by two pyrazine-2-carboxylate ligands. The distorted six-coordination is completed by two tin-bound methyl C atoms. The C2N 2O2 donor set defines a skewed trapezoidal-bipyramidal geometry. Intermolecular π-π interactions between the pyrazine rings [centroid-centroid distance = 3.8112(13)Å] are observed.
